Double-row rolling bearing

Abstract

A double-row rolling bearing, having a split inner ring, an outer ring, rolling elements, and at least one cage. The split inner ring having at least on inner ring race, and the outer ring (4) having at least one outer ring race. The rolling elements being arranged such that they are mutually spaced in the cage and roll between the inner ring and the outer ring, and the rolling elements being designed as rolling element rollers, and the bearing being designed in an X arrangement. The split inner ring is split into two annular inner ring parts, and the two inner ring parts are preloaded with a preloading means arranged therebetween.

1 . A double-row rolling bearing, comprising: a split inner ring, an outer ring, rolling elements and at least one cage, wherein the inner ring has at least one inner ring raceway and the outer ring has at least one outer ring raceway, wherein the rolling elements are arranged between the split inner ring and the outer ring so as to roll in the at least one cage at a distance from one another, and wherein the rolling elements are designed as rolling element rollers, and wherein the bearing is designed in an X arrangement,
 wherein the split inner ring is split into two annular inner ring parts and the two inner ring parts are preloaded with a preloading element arranged therebetween.   
     
     
         2 . The double-row rolling bearing according to  claim 1 , wherein the rolling element rollers are formed as spherical rollers. 
     
     
         3 . The double-row rolling bearing according to  claim 1 , wherein the preloading element is designed as a spring. 
     
     
         4 . The double-row rolling bearing according to  claim 1 , wherein the preloading element applies a preload F(axial) of between 0.0001 and 0.15*basic static load rating C0r of the rolling bearing to the inner ring parts. 
     
     
         5 . The double-row rolling bearing according to  claim 1 , wherein the preloading element applies a preload F(axial) of between 0.05+/−0.01*basic static load rating C0r of the rolling bearing to the inner ring parts. 
     
     
         6 . The double-row rolling bearing according to  claim 1 , wherein a movability of the two inner ring parts in an axial direction relative to one another is limited by at least one shoulder on one of the inner ring parts. 
     
     
         7 . The double-row rolling bearing according to  claim 1 , wherein the cage is formed of multiple parts. 
     
     
         8 . The double-row rolling bearing according to  claim 1 , wherein the at least one cage is guided on the outer ring. 
     
     
         9 . A bearing arrangement having a double-row rolling bearing according to  claim 1 , wherein the double-row rolling bearing has a shaft passing through it and the outer ring is mounted in a housing. 
     
     
         10 . The bearing arrangement according to  claim 9 , wherein the outer ring of the double-row rolling bearing is formed of two parts.
